Questions
How many USMLE Step 1 questions are in the bank?
The live count is at the top of this page, broken down by system in the coverage table. We do not quote a fixed number in this FAQ because the bank grows as items are added.
Are these AI-written?
Yes. They are AI-drafted from primary sources, checked by automated quality audits, and every item has a report button. Read how we make content on the About page, and use the report button on any item that looks wrong.
Do I need an account?
No. The sample questions on this page are free with no account and do not count toward the daily allowance. The full QBank lets you answer 5 questions a day without signing in, or 10 with a free Google account. Premium is unlimited.
Are these official USMLE Step 1 questions?
No. These are Hibbert practice items written to the published USMLE Step 1 blueprint. They are not retired or live exam questions, and Hibbert is not affiliated with the exam's governing body.
How is the USMLE Step 1 structured?
Multiple-choice only. Up to 280 questions in 7 blocks of 40. Reported as pass/fail. One day; about 8 hours including breaks. Details are from USMLE; see the official page linked in About the exam.
Do the sample questions count toward my daily limit?
No. Samples on this page are graded in your browser and never call the QBank answer endpoint, so they do not use the daily quota.
What happens if I get a question wrong?
You still see the explanation. With a free account, misses feed one objective graph across QBank, lecture quizzes, cases and simulations, and Focus Areas turns repeated misses into a study plan.
How do I report a problem?
Every question has a report button. You can also write from the About page. Reported errors are fixed in the source item.
